DEVICE FOR HANDLING MATERIAL.

Specification of Letters Patent.

Patented June 25, 1907.

' Application filed February 14,1907. Serial No. 357,347.

To all whmn it may concern.-

Be it known that I, THOMAS B. RIGE, Jr., a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Device for Handling Material, of whichthe following is a specification.

My invention relates to a new and useful device for handling materialand consists in providing a suitable support having a weight suitablyconnected therewith, whereby when the material is placed upon thesupport, by a slight pull upon the part of the operator, the saidsupport. and material will be lowered.

It further consists ofother novel details of construction, all as willbe hereinafter fully set forth.

In the drawings, I have shown a portion of a lock-corner machine towhich my invention is attached and that when in use on this machine, itwill be understood, the device is for handling boards. lVhile I haveshown the same as applied to the said machine, it will be understoodthat the device may be applicable and used for other purposes.

Figure 1 represents a partial sectional view and partial front elevationof a lock corner machine showing my invention as applied thereto. Fig. 2represents a partial sectional view and partial side elevation thereof.Fig. 3 represents in elevation, portions of the device in differentpositions from that seen in Fig. 2. Fig. 4 represents a partial planview and partial sectional view of a portion of the machine showing theboards in position. Fig. 5 represents a partial plan view of a portionof the device showing the boards at one end of the support 6 about to beclamped. Fig. 6 represents a partial plan view and partial sectionalview of a portion of the machine showing a few boards in position on thesupport 6 and showing the position of the front head 3.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings c-In lock-corner machines it is to beunderstood that a number of boards are placed together and are fed Bydevice, I am enabled to quickly and easily 'handle the boards and whileI have shown a construction for carrying out my invention, it will beunderstood that I do not desire to be limited in every instance to theconstruction as herein shown and described, as other instrumentalitiesmay be errliployed which will accomplish the same resu ts.

- 1 designates the base or frame of the machine having "uides 2 thereinin which moves the front head 3 and rear head 3, said heads carrying theextensions 21 and 22 respectively and being suitably conncted by meansof the threaded rod 23, one end of which is rotatably connected with therear head 3 and is in threaded engagement with a suitable opening in thefront head 3, said rod having a suitable gear 24: thereon meshing withthe idler 25 which is in mesh with the gear 26 which is on a shaftsuitablv mounted and adapted to be actuated bythe hand wheel 27, itbeing understood that by rotating the hand wheel 27 through the mediumof the. gears 24;, 25 and 26, the front head is caused to approach or tobe moved from the rear head 3 this being done for the purpose ofclamping the boards between the extensions 2]. and 22 carried by theheads respectively, it also being understood that after the heads areseparated the boards 28 are placed in position upon the support 6 withthe protectors 29 and 30 at the opposite sides of the boards, afterwhich the hand wheel 27 is suitably rotated to bring the heads 3 and 3together until the boards are positively looked upon the support 6between the extensions 21 and 22 of the heads.

31 designates a gear or pinion which meshes with a rack 32 carried bythe base which supports the heads 3 and 3 Upon power being imparted tothe gear 31, it will rotate and actuate the rack 32, in order to movethe heads 3 and 3 and with them the boards 28 and support 6, so that theboards will be brought into suitable position to be cut by the saws 4which are suitably supported and separated and carried by a suitablestationary portion of the machine.

It will be understood that Fig. 4c represents the boards locked inposition and the machine just ready to be actuated so that the boardswill be out by the saws, Fig. 6 showing the position of the boards afterthey have been cut and the extreme position to which the head 3 moves,that is to say, it will be understood that the head 3 never, passesbetween the saws. i

. 5 designates tracks or guides which are movably supported on each sideof the head 3 and movable in said guides are the sup ports 6 which, inthe present instance consists of angled bars, the lugs or extensions 7on the guides 5 assisting in the guidingof the supports. 8 designates across-bar with which said supports 'aresuitably connected and carried bysaid cross-bar is the eye 9, which is adapted to receive a standard 10carried by the head 3 on the machine, where by it will be seen that saidbar 8 is properly guided in its vertical movement. i

Connected with the supports 6 in the present instance, by the medlum ofthe crossbar 8, is a cord or cable 11, which is suitably connected withthe pivoted lever 12. In the present instance, the cord or cable 11passes over the pulleys 13 which. are suitably sup ported. The lever 12is pivoted at 14 to a suitable stationary support, said lever being.

provided with the movable weight 15 and is adapted to contact with astop 16 to prevent a too great depression of said lever.

17 designates an eccentrically pivoted suitable device 18, the oppositeend of said chain being connected with a stationary suport. iiected withthe rods 19, which are suitably carried by the frame 1 of the machine.The handle 20 is conveniently connected with the cross-bar 8 forimparting a pull thereon. The boards 28'which are to be provided withthe slots for the lock-corner are placed on the extension of the support6, the weight 15 having beenadjusted so that the boards will notimmediately lower the support from its upper position until the operatorpulls down on the handle 20 which will thus lower the support and raisethe weight 15. The boards are then looked in position as previously de-.

scribed and the pinion 31 actuates the rack 32, so that the boards arecarried past the saws in order that the ends of the boards are properlycut.

It will be noted that as soon as the support 6 is lowered and thecross-bar 8 passes the latch 17, the same will be thrown, by reason ofthe position of its pivoted point, into engagement with said cross-bar8, as will be best. understood from Fig. 2, and that said support willbe positively located in its proper position and held there. it beingunderstood that the locking of the boards betweenthe heads 3 and 3 alsoassistsin properly holding the support in position. As the heads 3 and 3with the boards thereon move to the rear of the machine, while theboards savers port and boards.

In the present instance, it .iscon- .are being passed through the saws,the

weight 15 w ll be slightly raised, but upon the return of the parts, theweight will be in the position for assisting in raising the sup- Afterthe boards, however, have assumed the position seen in Fig. 6, themovement of the pinion is reversed and the heads 3 and 3* are returnedto their former position or that seen in Fig. 2, so

"that the weight will be in proper position,

as seen in full lines then by a slight pull upon the lever 12, theweight 15 will be lowered "into the position seen in dotted lines, Fi 2,

end and to the latch 17 at the opposite end, the upper end of the latchwill be moved to the position seen in Fig. 3 by the tightening of thechain 18, that is to say, the latch is automatically removed fromengagement with'the cross bar 8and as the upper end of the latch withthe chain attached thereto passes over the pivotal point, it will beseen that the said latch will remain in the position seen in Fig. 3,while the heads 3 and 3 and parts connected therewith return to theposition seen in Fig. 2. The head 3 is now moved by the operating handle27 so as to 5 lever 17 throwing the same over so that the upper end withthe chain attached is upon the opposite side of the pivotal point butthe latch of said lever will not be in engagement with the cross bar,while the latter is elevated,

but as soon as it is lowered againwith another set of boards to be sawedthe latch will again engage the cross bar as'before.

Having thus described my invention, what I claim'as new and desire tosecure by Letters Patent, is r 1.
